摘要
设计一种具有方向图分集特性的两单元可穿戴天线,其中的一单元为平面倒F天线,具有垂直于人体表面无明显衰减的方向图特性,另一单元为顶端单极子,具有平行于人体表面的水平全向方向图特性,两单元均能实现对5.8GHz ISM频段的覆盖.由于天线单元间距很小(约0.048λ@5.8GHz),会有一定的耦合产生,通过公共地面上的开槽处理,在保持天线尺寸不变的前提下,减少了天线单元间耦合.
A two-element wearable antenna with radiation diversity characteristics was designed.One antenna element was a planar inverted-F antenna with no significant dips in the direction vertical to the surface of the human body,the other antenna element was a top monopole antenna which had a horizontal omnidirectional pattern in the plane parallel to human body,and the two elements could achieve coverage of 5.8 GHz ISM band.Since the distance between the antenna elements was small(approximately 0.048λ@5.8 GHz),some coupling effect would be generated.Therefore,the coupling between antenna elements was reduced by slotting the common ground while keeping the antenna unchanged.
